F.04: Performance Tuning
~~~~~~~~~~~~~~~~~~~~~~~~
You can tune your car during races or free roam. Open the Pause Menu and 
choose Performance Tuning. There are seven adjustable sliders:

F.04.a) Steering
~~~~~~~~~~~~~~~~
- You must install a Suspension upgrade to access this tuning slider.

"The steering slider lets you control how quick the steering response is. 
Moving the slider to the right will increase the steering quickness while 
moving it to the left will decrease the steering quickness. Quicker 
steering is usually better as long as you are able to still control your 
car."

If you're a really good driver, you can combine quicker steering with lower 
ride height and more downforce to take turns a lot quicker. Otherwise, 
leave this at default or turn it down one notch. For drag races, you will 
want this turned up one or two notches for quicker dodging of traffic.

F.04.b) Handling
~~~~~~~~~~~~~~~~
- You must install a Suspension upgrade to access this tuning slider.

"This slider allows you to tailor your car's handling to suit your driving 
style. If you would like your car to slide a little more, move the slider 
to the left. If you like your car to slide less, move the slider to the 
right."

Leave this at default or move it right one stop unless you're really good 
at powersliding through turns, then move it left one or two stops.

F.04.c) Brakes
~~~~~~~~~~~~~~
- You must install a Brake upgrade to access this tuning slider.

"This slider lets you adjust the brake bias of your car towards the front 
or rear. Adjusting the brake bias to the front or rear will affect how much 
your car is able to turn while braking. Adjust the slider to the right to 
move the brake bias forward and adjust it to the left to move the brake 
bias toward the rear."

Rear-wheel drive cars will want a little more brake on the front end to 
keep from going completely out of control in a turn. Front-wheel drive cars 
will want a little more brake in the rear for the same reason. All-wheel 
drive cars can leave the setting at neutral.

F.04.d) Ride Height
~~~~~~~~~~~~~~~~~~~
- You must install a Suspension upgrade to access this tuning slider.

"This slider allows you to raise or lower your ride height. Moving the 
slider to the right will raise the ride height, while moving it to the left 
will lower the ride height. Generally, a lower ride height improves 
handling but can also make your car harder to control if the road is not 
smooth."

Lowering your car will help you cornering, but is probably a bad idea 
considering all the off-road shortcuts and rough patches you hit during the 
game. You can probably leave this setting alone or move it left one notch. 
There's really no need to raise your ride's height.

F.04.e) Aerodynamics
~~~~~~~~~~~~~~~~~~~~
- You must install a Body Kit or Spoiler upgrade to access this tuning
  slider.

"This slider allows you to increase or decrease the overall downforce on 
your car. Increasing the downforce will help your car stick to the road but 
will affect your top speed. If you like your car looser and more likely to 
slide, try decreasing the downforce."

Putting a spoiler on your car and increasing the downforce will definitely 
help you stay in control when cornering. Considering how many races require 
good handling over high speed, the hit to your cars top speed won't be that 
big a deal. For tollbooth trials and drag races, you can decrease the 
downforce and pick up a little bit of speed on the high end.

F.04.f) Nitrous
~~~~~~~~~~~~~~~
- You must install a Nitrous upgrade to access this tuning slider.

"Adjust the slider towards the left for a longer but less powerful N2O 
boost. Adjust it towards the right for a more powerful boost but with less 
duration."

In most situations, you want to use quick boosts of nitrous to help you 
straighten out of a slide or get into the next gear. Set your nitrous 
slider a point or two right to get more grip when coming out of 
powerslides. For drag races, adjust it two or three points left to get 
longer bursts down the home stretch.

F.04.g) Turbo/Supercharger
~~~~~~~~~~~~~~~~~~~~~~~~~~
- You must install a Turbo or Supercharger upgrade to access this tuning
  slider.

"This slider lets you adjust the characteristics of your induction system. 
Move the slider to the right to shift your torque boost into a higher RPM 
range. You'll sacrifice boost in the lower RPM ranges but will gain more 
torque at the top end. This is useful for high speed tracks. Move the 
slider to the left to spread the torque boost across a larger range of 
RPM's. This is useful for tighter tracks where you need boost while 
accelerating out of corners."

Move this slider right for tollbooth trials and drag races. Move it left 
for most other events, including police pursuit.
